Private Cloud For Dummies

Observe the sky. There may be several types of clouds in the sky, including cirrus, cumulus, nimbostratus, and stratus. This book does not discuss certain types of clouds. Consider instead the clouds that offer computational services, consume power, and are connected to the Internet.

A Menagerie of Cloud Computing

The cloud is the most fundamental animal in this zoo since it alludes to cloud computing. This term refers to a computer environment in which computing resources, particularly data storage, networking, and processing power, are accessible on-demand without needing active, direct administration by its users.

Cloud users are often "here" (from their viewpoint, at least), whereas cloud computing resides "elsewhere" (frequently in a data centre). As it turns out, there are also different types of computing clouds (often in interesting combinations, just like real clouds). Here are some words you'll need to consider and comprehend to comprehend the plot of this book.

Depending on who owns, manages, and runs them, clouds have two distinct types:

Public cloud - A public cloud is accessible on-demand and via subscription. It's the cloud you've heard so much about, and it comes from a variety of providers, such as Amazon (Amazon Web Services, or AWS), Microsoft (Azure), Google (Google Cloud Platform, or GCP), etc.

Private cloud - A private cloud serves a single business or organization that owns and controls at least all of its material. A private cloud need not exist on-premises since a third party may host it in its data centres or the owner can host it in its own data centre (or centres). However, it frequently does just that.

Clouds also appear in a variety of quantities, with multiple clouds including some kind of combination. Here's what's going on:

Single cloud - Represents a scenario in which a corporation or organization use a single supplier or solution for cloud-based applications or infrastructure. This arrangement is very uncommon, if not unheard of, in the current market.

Multi-cloud - Refers to a company or organization that utilizes two or more cloud providers or solutions for its cloud applications or infrastructure. Some multi-clouds have little or no interoperability among their component clouds. Other multi-clouds permit workload and data migration between component clouds. The former is known as a multi-cloud with poor interoperability, whereas the latter is a multi-cloud with strong interoperability.

Hybrid cloud - A variant on multi-cloud, a hybrid cloud allows one or more applications to operate smoothly across its component clouds with simple orchestration and management.

Management of the Cloud: On- and Off-Premises

The majority of firms of any size use several public and private clouds throughout their departments and operations. However, the idea of all potential worlds is one in which all clouds operate in unison and offer a single, uniform, and coherent face to their users and the IT experts responsible for putting them up and keeping them operational.

A worldwide, company-wide perspective on cloud computing is best tackled and maintained as a "enterprise cloud environment." This requires the use of tools and solutions that integrate operations across all clouds and provide interoperability for all business workloads.

This consolidates on-premises and off-premises clouds, as well as their applications and data assets, under a single "pane of glass" with a centralized point of management for all apps and data. Regardless of whether the cloud is public, private, or a hybrid of the two, this gives the ability to control expenses, ensure consistent security, and fulfil the service-level agreement (SLA) needs for application and service delivery. The objective is to put and manage workloads where they will provide the greatest outcomes (and best economics) and to relocate them as required.
